Julie Buck has a lot of friends. For Finite Sets she sorts her friends from various times, places, and circumstances into Venn diagrams. A Venn diagram represents separate, closed sets in circles and shows the sets relations by overlapping regions. Inside each of Julie's circles is a self-portrait and within every friend set a change in identity shows clearly on her stark, silhouetted face. So while the term has temporarily crept into our vocabulary, consider this a facebook that shows a friend network, as well as identity’s ever-changing face, within a set of connections.
